Toggle display of generic debugging messages.
-- ``CONFIG_RTE_LIBRTE_ICE_RX_ALLOW_BULK_ALLOC`` (default ``y``)
-
- Toggle bulk allocation for RX.
-
- ``CONFIG_RTE_LIBRTE_ICE_16BYTE_RX_DESC`` (default ``n``)
Toggle to use a 16-byte RX descriptor, by default the RX descriptor is 32 byte.
The APPs based on DPDK should avoid providing such packets.
+Device Config Function (DCF)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This section demonstrates ICE DCF PMD, which shares the core module with ICE
+PMD and iAVF PMD.
+
+A DCF (Device Config Function) PMD bounds to the device's trusted VF with ID 0,
+it can act as a sole controlling entity to exercise advance functionality (such
+as switch, ACL) for the rest VFs.
+
+The DCF PMD needs to advertise and acquire DCF capability which allows DCF to
+send AdminQ commands that it would like to execute over to the PF and receive
+responses for the same from PF.

+ DCF Communication flow.
+
+#. Create the VFs::
+
+ echo 4 > /sys/bus/pci/devices/0000\:18\:00.0/sriov_numvfs
+
+#. Enable the VF0 trust on::
+
+ ip link set dev enp24s0f0 vf 0 trust on
+
+#. Bind the VF0, and run testpmd with 'cap=dcf' devarg::
+
+ testpmd -l 22-25 -n 4 -w 18:01.0,cap=dcf -- -i
+
+#. Monitor the VF2 interface network traffic::
+
+ tcpdump -e -nn -i enp24s1f2
+
+#. Create one flow to redirect the traffic to VF2 by DCF::
+
+ flow create 0 priority 0 ingress pattern eth / ipv4 src is 192.168.0.2 \
+ dst is 192.168.0.3 / end actions vf id 2 / end
+
+#. Send the packet, and it should be displayed on tcpdump::
+
+ sendp(Ether(src='3c:fd:fe:aa:bb:78', dst='00:00:00:01:02:03')/IP(src=' \
+ 192.168.0.2', dst="192.168.0.3")/TCP(flags='S')/Raw(load='XXXXXXXXXX'), \
+ iface="enp24s0f0", count=10)
